You clearly have no clue what you're talking about. These protests are about people being angry that Sanchez might offer amnesty to those catalunyans who broke the law by having an illegal rather than legal referendum.

Most people didn't support the referendum, it had already been ruled illegal, and only those that were separatist voted.

Again, you do not understand how a multi party parliament works. Sanchez didn't really lose the election. The left wing parties got as many seats as the right wing parties with the junts sitting in the middle as mild king makers (they cannot help the right, they can only cause another election in which they will likely get wiped out).

And again, if Sanchez and the PSOE do not form a government but the PP and Vox do, then Spain will be ruled by an authoritarian ultra right nationalist party that has stated they intend on putting more national police and Guardia civil in Catalunya to prevent even protests.

Yet somehow, in all your political wisdom, are angry that Sanchez might give assistance to the people in trouble for having the referendum and thus he should be ousted so that the fascists can come in to power?
